Sr; a seaport of France, capital of an arrondissement of the same name in the department of Ille-et-Vilaine, is situated on the island of Aron, which is joined to the land by a narrow causeway called the Sillon, about three-quarters of a mile in length, 45 miles N. by W. of Rennes; Lat. 48° 39', N., Long. 2° 1', W. The harbour is secure, being sheltered from the sea by the island and the Sillon; but the great number of rocks render the approach both difficult and dangerous. To the W. of the town there is a roadstead, which is separated from the harbour by a chain of rocks, and defended by seven forts. The harbour is dry at low water, but has recently been improved by the formation of a large wet dock. The harbour is much frequented: vessels are fitted out here for India and for the whale fisheries, and a good deal of ship-building is carried on. The chief articles of export are the products of the surrounding country, together with straw hats, woollen and linen fabrics; and it imports sugar, indigo, spices, and other Indian and Chinese wares. The town is strongly fortified, the defences being constructed by Vauban. At the entrance of the town from the Sillon there is an ancient castle of an imposing appearance, built of granite, and having a strong tower at each corner. The fortifications rise abruptly from the water's edge, and the whole surface of the island is covered by the town. The houses are lofty and built of stone; and there is a square in the centre, in which stands the cathedral, the Hotel de Ville, and the episcopal palace. Not far from the town is St Servan, which is sometimes considered as a suburb of St Malo. The manufactures of St Malo consist mainly of sail-cloth, cordage, fish-hooks, hosiery, and soap. This town seems to have been founded in the tenth century; but the island on which it stands was the seat of a monastery as early as the sixth century. Before the rise of Brest, this town was the first seaport in France on the ocean; and Cartier, one of its seamen, was the discoverer of Canada. During the wars with Great Britain the privateers of St Malo did so much injury to their enemies, that the town was three times bombarded by the British, in 1693, 1695, and 1758, but always without success.
